Part Number: MSP430FR2111 Hi All Customer meet a issue that when P1.6 select to TB function and firmware change its setting from TB0.1 to TB0.CCI1A, the P2.0 GPIO output will change from high to Low by device itself. I double check the register setting on watch window, and confirm P1SEL.6 = 10 (P1.6 is TB function), P1DIR.6 = 1 (P1.6 is TB0.1 function); P2SEL.0 = 00 (P2.0 is GPIO function), P2DIR.0 = 1 (P2.0 is output). and SYSCFG3.TBRMP = 0 (CCI1A set to P1.6). In this case, we test P2OUT.0 set to 0 or 1, the P2.0 can measure output low or high by normally. However once we change P1DIR.6 from 1 to 0 (P1.6 set to TB0.CCI1A), the P2.0 will measure keep low level no matter P2OUT.0 is 0 or 1. May I get your help advice? Another question Customer use P1.6 as TB0.CCI1A to capture external pulse, however P1.6 in FR2111 has not wake up function, so customer connect P1.6 and P1.0 together, use P1.0 to wake up FR2111 from LP3 mode and P1.6 to capture by same external pulse. Do you think if it is ok for such usage?
